30 year mortgage rates are around 3.65% this week. So if a buyer puts down 20%, that will be around $259k in interest over the life of the $400k loan, putting the total interest at half of what you said (~$760k total the life of the loan ve

Yeah I guess that explains the fond memories part. Some 32-bit parts are totally flat. Like low-end ARM parts with SRAM and no MMU. Compare that to a 8-bit or 16-bit PIC microcontroller where you need to bank switch to have a usable amount

Totally agree. I've been making the same argument elsewhere on this thread. People are disagreeing with saying things were simpler back then. I don't know how anyone can have fond memories of a 16-bit CPU with segments or bank swi

It does though, if you mix near and far pointers, you are going to be getting crashes. Pointer equality and comparison are non-trivial. Whereas on a modern 32-bit CPU you don't have any such distinction.

A 16-bit space is not at all simplified, it's far more complex. Because of that, it is a terrible choice. It's a much more difficult memory model to learn in. In a flat 32-bit address space, a pointer is a pointer and it just work

I remember hearing about these around 2008 and then the application being pushed was no cables to your fancy flat screen TV. Blu-ray player uses UWB RF so no cables are necessary. I don't think anyone saw then the end of physical media

Sure you can learn a lot but I have no idea why you would choose Turbo C in 2020 over say a Raspberry Pi with GCC. Turbo C (discontinued in 1990) is going to expose a bunch of irrelevant things today, as even most microcontrollers are 32-bi

Definitely true. People also seem to forget the Red River basin (e.g., North Dakota, Minnesota, Manitoba) that flows north to Hudson Bay was a massive lake about 10,000 years ago called Lake Agassiz. So its periodic flood pattern is expecte

Some things are much easier with ODB electronics though. Like if a cylinder is misfiring, you pull out a code scanner and see exactly which spark plug needs to get replaced.

I mean that sounds more like "It's a pain in the ass to change a headlight in my girlfriend's car, so I have her bring it to a shop" than a right to repair issue. Or are you saying the shop needs special tooling to get t

Yes this and it is also much harder to switch off a heavy DC load than an AC one. Once current starts flowing in DC and you try to open a switch, an arc will form that never gets extinguished since the voltage doesn't cross 0 like it d

Turbo codes are typically soft decision codes, which don't make a ton of sense at the filesystem level, since there has already been a hard decision made. They are useful in storage at the read channel level, as in processing the analo

Curious - what are your complaints on these programs? My main one is that they are slow to create archives and rsbep only does error decoding, not erasure. I'm working on an alternative tool that is much faster, but curious if you have

This is not true. I have encountered several times on systems with ECC memory where MD5 values for large archives change on magnetic discs. No read errors or SMART errors. I have a HDD (1TB Western Digital Green) in my desk drawer that does

Sure, but there is no way this should be used as a reference in 2019. It was wrong even in 2003 when it was written - Unicode 3.0 from 1999 defined the maximum number of code points, surrogate pairs, and code points above U+FFFF. His single

I just read this over and it's a very dated Windows-centric view. Several glaring errors - glosses over the difference between UCS-2 and UTF-16, no mention of surrogate pairs for UTF-16 (thinks only 65k code points), says UTF-8 can be
